I Help Self-Taught Pianists Play With Confidence & Creativity
Real Piano Freedom
True Piano Mastery is an educational platform for (aspiring) pianists who want to play music on their own terms.
Traditional teaching methods have it backwards: instead of guiding your personal growth as a musician, they lock you into rigid schedules and one-size-fits-all systems. Despite trying your best, it's easy to lose motivation. Many quit before discovering the joy of real music-making.
We do things differently. Our tools are developed with you, the pianist, in mind, helping you build essential skills at your own pace, so you can unlock true musical independence, one step at a time.

Built from Experience
I'm Thomas Jonker, a pianist, arranger, and educator from Amsterdam.
After years of struggling with traditional piano lessons, I decided to take control of my own learning. That decision completely changed my experience.
Instead of working through pieces and exercises I didn’t connect with, I focused on the music I loved most, fueling my passion and consistency.
Through self-study across different genres, I slowly developed my own playing style. One that now resonates with millions worldwide.
To help other pianists experience that same sense of freedom, I started True Piano Mastery,
